DAVID S. NASH, OF CORSICANA, AND JAMES E. LETT, JR., OF DALLAS, TEXAS.

ROAD LOG AND MAP DISPLAY DEVICE.

Application filed April 2, '1925;

`To @ZZ whom 'it m04/ concern:

. Be it known that we, Davie S. NASH and .latins E. Ln'r'r, Jr., citizens oftheUnited States of America, residing` at Corsicana, Navarro County, Texas, and in Dallas, in [he county of Dallas and State of Texas, respectively, have. invented certain new and useful Improvement-s in Road Log and Map Display Devices, of which the followingl is a specification.

This invention relates to new and useful improvements in road log and map display devices. The object of the invention is'to co-ordinate a road log with a road map in a new and novel manner.

A further object is to provide means for exhibiting a road log so as to give the route in either direction between two given places.

Another object is to provide a device of the character described which may be installed at the road side or other point of information and provided with a display panel on which any desired matter may be exhibited.

A construction designed to carry ont the invention will be hereinafter described together with other featuresof the invention.

The invention will be more readily un derstood from a reading of the following specification and by reference to the accompanying drawings, in which examples of the invention are shown, and wherein:

Fig. 1 is a front elevation of a device constructed in accordance with our invention,

Fig.' 8 is an enlarged cross-section takenl on the line S--S of Fig. 5.

In the drawings the numeral 10 designates a vertical cabinet having side walls 11, and a rear wall 12 with a false rear wall 13'. The front edges of the side walls are connected by a cross brace bar 111-. A cylindrical housing 15 is supported at its ends in semi-circular seats 16 cut in the upper ends of the Serial No. 20,201.

side walls infront of the false wall 13. This housing has a longitudinal slot or opening e posite sides of the partition 20. The outer end of each drum is mounted on a stub shaft 23 journaled in the end of the house ing and having a crank handle 24. The drums may be made solid kor hollow.

On the surface of each drum is printedA or' 'otherwise applied 1n any suitable manner, p On the drum 18 the road is a road log. logged in one direction between two cities and on the drum 19 the same road islogged in the opposite direction between the saine cities. For instance on the drum 18 the road from Dallas to Houston, Texas, maybe displayed; while on the drum 179,v the return vroad from Houston to Dallas may be shown, but this is not essential as two different routes may be logged on the drums. Either drum may be revolved independently, of the otherby means of its crank handle 24g.

Each trunnion 21r has a circumferential groove 25 for receiving a cord 26. which is wound therein when the drum is revolved.

Each end of the cord'is fastened to one of the trunnions and said cord passes through apertures 27 in the false walls 13 which eX tends above the walls 11. The cord is looped around Y'a pulley 28 at the rcenter of the bottom of a map slide or board 29. The looped portion depends from lpulleys 30 mounted in the space between the wall`13 and said slide, below a cap 31 closing the upper end of said space.

It will be seen that when either drum is revolved to wind the cord 26 thereon, the

slide 29 will be raised. On the Vface of the slide maybe displayed map (not shown) on which the routes logged on the drum maybe shown with adjacent towns and any other desired information. A display panel 32 may be fastened to the rear side of the wall 12 so as to extend above the top of the cabinet and advertising and other data may be displayed thereon. Any suitable means for guiding the slide 29 may be employed.

ln Figs. 5 to 3 we have illustrated an alternate form of the invention in which the only c liffeienee resides in the construction of the drums and the cord connection for raising the map slide, otherwise the parts are thesame.. Infthisform the drums 1S and 19 are made integral and the central partition 20 is eliminated. f Thev drums are separated by a central circumferential groove 38 in which one end ofE a cordl is fastened.. This cord passesthrough an aperture 27in the false' wall 13, over a pulley 30y andlias'its dependingjend fastenedby a screw or-thelike 35 to the lower end of the slide 29. y,lVhileboth drums will be re'- volvedyat the same time, the user may ob,` serve etitlie'r or both.

Various changes inthe size and shape or the dii'lerentparts", as well as modifications and' alterations may be made within Jthe scope of' the appended claims.`
